Where can I upload or submit the result of my second PCR test in Thailand?

My test & go hotel did it for me as well.

The link in the notification you get from the app is dead, I don’t see how you can upload it via the link. I tried copy pasting into chrome, but that didn’t work either.

Like Jim mentioned, I think your safest bet is to have the hotel do it.

The hotel did it for me. I stayed in pattaya for the test and go, but did my 2nd pcr test in buriram. I emailed the hotel the result and asked them to submit it the same way they did the test and go result. They were happy to do it for me they said. Not sure what I'd have done if they did not cooperate as like you the app supplied was crap and I couldn't see a way to upload it either. Suggest you ask the hotel nicely if they would do the same as me.
